Sport bike motorcycle fairing accessory

ABSTRACT

A wind-shielding device for motorcycles, particularly for modern sport-style motorcycles commonly termed, “sportbikes”. The device affords operators of sportbikes a means to enjoy motorcycling during winter months or any other time when the outdoor temperature is below that generally considered ideal for motorcycling, as typical of early spring and late fall, without enduring direct exposure to frigid on-coming air. The device conforms to and fits over a sportbike&#39;s factory-installed (original equipment) fairing and vastly improves wind protection. The present invention can be fabricated of an inexpensive and sufficiently rigid acrylic, polycarbonate, fiberglass, or other suitable material using common molding techniques. The device also protects the motorcycle&#39;s original equipment fairing and painted surfaces from potentially damaging stones and other airborne road debris.

BACKGROUND OF THE INVENTION

This invention pertains to the area of windshields (windscreens) and fairings for motorcycles, particularly for modern sport-style motorcycles commonly termed, “sport bikes.” The present invention is an accessory fairing for sport bikes. It conforms to and fits over a sport bike's factory-installed fairing and vastly improves wind protection. The primary intent of this device is to afford operators of such motorcycles a means to enjoy motorcycling during early spring, late fall, and winter without enduring direct exposure to frigid on-coming air. The present invention can be fabricated of a readily-available and inexpensive acrylic, polycarbonate, fiberglass, or other suitable material. The present invention can be easily installed, thereby allowing the motorcyclist, regardless of his or her level of hands-on mechanical ability and experience, to set up his or her motorcycle for cold weather riding. The present invention also protects the motorcycle's factory fairing and painted surfaces from potentially damaging stones or other airborne road debris.

Sport bikes are purpose-specific, high-performance vehicles. These motorcycles are designed for high speeds and accelerations and are commonly used in professional and amateur closed-course competitions. Like all other essential components of a sport bike, the factory-installed fairing plays an important role in the sport bike's performance capabilities. Sport bike fairings are specially engineered to minimize the motorcycle's drag to facilitate the highest possible speeds. The fairing's efficient aerodynamic shape and size however, inherently offer minimal wind protection for the sport bike rider; this is why in early spring, late fall and winter, when outdoor temperatures can be below that generally considered ideal for motorcycling, operating a sport bike can be uncomfortable or intolerable for most riders.

Some sport bike riders address the cold-weather issue, however, with only limited effectiveness, by installing a “tall” windscreen. The windscreen, which is the upper middle portion of the motorcycle's fairing assembly, is easily removed and replaced since it is commonly fastened with simple screws. Domestically sold sport bikes are equipped with windscreens that are typically made of a clear, colorless plastic by original equipment manufacturers (OEM).

In recent years, an explosive global growth in the popularity of sport bikes has occurred. Correspondingly so, the availability of “aftermarket” performance components and accessories for sport bikes has rocketed. While manufacturers of aftermarket products now offer replacement windscreens, which are available in a myriad of colors and match the size and shape of OEM units, for nearly all sport bike models, the manufacturers of aftermarket products only offer “tall” replacement windscreens for a relatively small number of sport bike models. More important, the “tall” replacement windscreens currently available offer marginally improved wind protection over OEM windscreens. The present invention however, immensely improves wind protection over factory-installed fairings and windscreens because it is both taller than OEM and OEM replacement windscreens and wider than the entire factory-installed fairing assembly. The present invention shields more of the rider's upper body and provides wind protection to his hands; no current factory-installed sport bike fairing or aftermarket windscreen for a sport bike shields the rider's hands. The use of the present invention therefore, can effectively extend the riding season for sport bike owners in geographical areas where winter and winter-like temperatures normally preclude pleasurable motorcycling.

Prior art are limited in effectiveness and applicability. The present invention however, overcomes the shortcomings of prior art, solves art-related problems, and offers uniqueness in technological design and functionality. Known prior art include all listed herein: 5,458,390 Gilbert October 1995 5,855,404 Saunders January 1999 6,017,076 Belisle January 2000

The proceeding discussions of the above cited patents clearly illustrate how the present invention discloses new and preferred embodiments.

U.S. Pat. No. 5,458,390, issued to Gilbert; describes an “enclosure assembly” that uses rigid support members attached to a touring-type motorcycle to form a cage-like frame around the entire motorcycle. Gilbert's device further utilizes a fabric cover connecting the rigid support members; the fabric cover and rigid support members together create an enclosure that shields the motorcycle operator (and passenger) from wind and rain. While Gilbert's device appears to offer an effective means for protection from harsh weather conditions for “touring bikes,” it is unsuitable for sport bikes. Such a device installed on a sport bike would prevent the sport bike operator from effectively negotiating turns. At moderate to high speeds, the sport bike operator must be free to extend his leg and knee outward in the direction of a turn to successfully negotiate the turn; Gilbert's device unquestionably precludes extending of the leg and knee and greatly reduces a sport bike operator's ability to shift his body weight from one side of the motorcycle to the other. Additionally, Gilbert's device is not suitable for sport bikes since it would significantly diminish a sport bike's available ground cornering clearance (lean angle). The present invention, however, does not adversely affect the ability of the sport bike rider to maneuver his body to negotiate turns or impact a sport bike's lean angle.

U.S. Pat. No. 5,855,404, issued to Saunders, teaches a fairing design that effectively extends the height of a motorcycle windscreen. As shown in FIGS. 2 and 3 of Saunder's patent specification, the device attaches to the upper portion of a motorcycle windscreen via a complex combination of mechanical connectors and support arms. The connectors and support arms are said to be “removably connected” to the motorcycle using “hook and loop” type “fastener patches”. These kinds of fasteners have been used in the clothing industry for decades. They are usually sewn onto fabrics and take the place of buttons, laces, or zippers, to provide a means for securing and closing garments, shoes, bags, etc. The use of “hook and loop” fasteners for mounting mechanical devices, such as Saunder's fairing, onto motorcycles poses the following potential drawbacks: 1.) The adhesive used to secure the fasteners must adequately perform in the presence of substantial vibration and all weather conditions (One would not attempt to sew “fastener patches” onto a motorcycle or a motorcycle windscreen thus, it is presumed Saunder's device requires the use of an adhesive to attach the “fastener patches.”), and 2.) The device would be easy for thieves to remove. Saunder's mounting system for his fairing device poses yet another potential problem; the support arms, which mount on the motorcycle body as shown in FIGS. 1 and 2 of Saunder's patent specification, preclude the use of popular “tank bags” that provide a convenient means for carrying cargo on top of the motorcycle's gas tank. The present invention, however, uses a simple and effective means for mounting to a motorcycle without taking up the surface space available on the gas tank. Additionally, the present invention offers improved wind protection over Saunder's invention since Saunder's invention does not effectively extend the width of a motorcycle fairing assembly and does not provide wind protection for the motorcycle operator's hands.

U.S. Pat. No. 6,017,076 issued to Belisle, describes a bubble-like enclosure for a motorcycle. Belisle's device is unsuitable for sport bikes for all of the reasons cited in the preceding discussion regarding U.S. Pat. No. 5,458,390.

SUMMARY OF THE INVENTION

The present invention is a novel and unique means for providing substantial wind protection for the operator of a sport bike. The present invention mainly conforms to the shape and size of a sport bike's factory-installed fairing for the purposes of fitting closely over a factory-installed fairing of a sport bike. The present invention features a central portion that departs (upward) in curvature from that of the windscreen of the factory-installed sport bike fairing to facilitate substantial wind protection for the sport bike operator's upper body. The present invention also deviates in gradient from the sides of the factory-installed sport bike fairing, extending outward on both left and right sides, to provide wind protection for the operator's hands.

It is also the object of the present invention to allow for reliable and straightforward installation of an effective means for substantial wind protection for an operator of a sport bike. In a particular configuration of the present invention, the present invention utilizes the mounting points of a sport bike's rear-view mirrors for fastening and shares the bolts (or other fasteners) used to attach the mirrors. The present invention also incorporates holes or voids that are located or spatially arranged in a pattern that corresponds to or suitably aligns with the locations of the factory-installed fasteners for the factory-installed fairing to allow either the use of the factory-installed fasteners or the use of other fasteners, in place of the factory-installed fasteners for the factory-installed fairing, for mounting the present invention. The present invention further incorporates a means, such as a flange, to adjoin a simple bracket, combination of brackets, and/or a bracket installed as original equipment rigidly connecting the frame of a sport bike, for mounting.

It is further the object of the present invention to provide an effective means for substantial wind protection for an operator of a sport bike which can be simply and economically manufactured. The present invention can be fabricated of inexpensive plastics, fiberglass or other like material that is suitable for common molding processes.

Yet another object of the present invention is to provide an effective means for substantial wind protection for an operator of a sport bike which does not detract from the sporty good-looks of a sport bike. As described above, the geometry of the present invention follows the contour of a sport bike's factory-installed fairing, resulting in an aesthetically pleasing and “finished” OEM appearance instead of the ruining look of a jerry-built, after-thought component. The present invention can be made transparent, using a material such as acrylic or polycarbonate, or painted, presumably matching a sport bike's factory paint color and scheme.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIG. 1, the present invention comprises fairing accessory 20 and bracket 30. Fairing accessory 20 mounts directly over upper fairing assembly 11 of modern sport bike 10. Bracket 30 provides for a rigid connection between flange 21 of fairing accessory 20 and a suitable point on modern sport bike 10 at a location below or behind upper fairing assembly 11 of modern sport bike 10. Bracket 30 can be configured to rigidly attach to modern sport bike 10 in different suitable locations including one of or all of the following: the outer surface of the steering column of modern sport bike 10, the inner surface of the steering column of modern sport bike 10, and a bracket installed as original equipment on modern sport bike 10 which may support upper fairing assembly 11 of modern sport bike 10. Mounting of fairing accessory 20 requires removal of rear-view mirrors 12 of modern sport bike 10. Fairing accessory 20 features holes 22, which align with the mounting points of rear-view mirrors 12 on upper fairing assembly 11, to allow use of fasteners to reattach rear-view mirrors 12 of modern sport bike 10 and secure fairing accessory 20 to modern sport bike 10. Fairing accessory 20 also features holes 99, which, when fairing accessory 20 is emplaced over upper fairing assembly 11, correspond to the location(s) of factory-installed fasteners 98 for lower fairing 80 and upper fairing assembly 11, to provide for additional means for mounting fairing accessory 20.

Referring to FIG. 2, fairing accessory 20, made of a transparent material, is mounted on modern sport bike 10. Fairing accessory 20 extends vertically beyond the top of windscreen 25 of upper fairing assembly 11 and horizontally beyond handlebar(s) 200 of modern sport bike 10. The present invention includes elastic, self-stick buttons 23 affixed at various locations on inner surface of fairing accessory 20 to prevent contact between inner surface of fairing accessory 20 and outer surface of upper fairing assembly 1I1 of modern sport bike 10. (The elastic, self-stick buttons 23 are similar to those commonly used on inner surfaces of residential kitchen and bath cabinet doors that serve as “bumpers.”) While the elastic, self-stick buttons 23 maintain a “gap” or “space” between the fairing accessory 20 and the upper fairing assembly 11 of modern sport bike 10 to preclude possible chafing that could result from vibration, the elastic self-stick buttons 23 also provide a means for vibration and shock isolation.

Referring to FIG. 3, the present invention comprises fairing accessory 20 and bracket(s) 40. Fairing accessory 20 mounts over and partially covers upper fairing assembly 11 of modern sport bike 10. Bracket(s) 40 provides for a rigid connection between flange(s) 24 of fairing accessory 20 and a suitable point on modern sport bike 10 at a location below or on the side of upper fairing assembly 11 of modern sport bike 10 and/or on the side of lower fairing 80 of modern sport bike 10. Bracket(s) 40, which has holes 100 that align with factory-installed fasteners 98 of lower fairing 80 and upper fairing assembly 11, can be connected to modern sport bike 10 using factory-installed fasteners 98 of lower fairing 80 and upper fairing assembly 11 or by using other fasteners in place of factory-installed fasteners 98. Mounting of fairing accessory 20 requires removal of rear-view mirrors 12 of modern sport bike 10. Fairing accessory 20 features holes 22, which align with the mounting points of rear-view mirrors 12 on upper fairing assembly 11, to allow use of fasteners to reattach rear-view mirrors 12 of modern sport bike 10 and secure fairing accessory 20 to modern sport bike 10.

Referring to FIG. 4, fairing accessory 20, made of a transparent material, is mounted on and partially covers upper fairing assembly 11 of modern sport bike 10. Fairing accessory 20 extends vertically beyond the top of windscreen 25 of upper fairing assembly 11 and horizontally beyond handlebar(s) 200 of modern sport bike 10. The present invention includes elastic, self-stick rubber buttons 23 mounted at various locations betveen inner surface of fairing accessory 20 and outer surface of upper fairing assembly 11 of modern sport bike 10 to prevent contact between inner surface of fairing accessory 20 and outer surface of upper fairing assembly 11 of modern sport bike 10. (The elastic, self-stick rubber buttons 23 are similar to those commonly used on inner surfaces of residential kitchen and bath cabinet doors that serve as “bumpers.”) The elastic, self-stick rubber buttons 23 maintain a “gap” or “space” between the fairing accessory 20 and the upper fairing assembly 11 of modern sport bike 10 to preclude possible chafing that could result from vibration.

Referring to FIG. 5, the present invention comprises fairing accessory 20 and bracket 50. Fairing accessory 20 mounts over upper fairing assembly 11 of modern sport bike 10 and bracket 50. Bracket 50, which is wedge-shaped and allows fairing 20 to fit and mount as an integral part of upper fairing assembly 11, provides for a rigid connection between fairing accessory 20 and modern sport bike 10 without requiring the removal (and reinstallation) of the mirrors of sport bike 10. The fastener hole pattern of bracket 50 and location of holes 52 of fairing accessory 20 match the fastener pattern of windscreen 25 of upper fairing assembly 11 so that bracket 50 can be “sandwiched” between upper fairing assembly 11 and fairing accessory 20 using fastener(s) 51 in locations of factory-installed fasteners for windscreen 25. It should be obvious to those with ordinary skill in the art that fairing accessory 20 could be designed and fabricated with holes 52 spatially arranged to match female-threaded holes or studs emplaced in bracket 50 at locations not corresponding to fastener locations of windscreen 25 to allow mounting (and removal) of fairing accessory 20 without removing fasteners used to secure bracket 50. It should be further obvious to those with ordinary skill in the art that fairing accessory 20 could be designed and fabricated with bracket 50 as an integral feature and that fastener locations on upper fairing assembly 11 other than those for windscreen 25 could be used to secure fairing accessory 20.
